Question No: 19      ( M - 2 )
What is a truth Table?

A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, Boolean functions, and propositional—to compute the functional values of logical expressions on each of their functional arguments, that is, on each combination of values taken by their logical variables .In particular, truth tables can be used to tell whether a propositional expression is true for all legitimate input values, that is, logically valid.

Question No: 20      ( M - 3 )
How learning to design programs is like play soccer?

Learning to design programs is like learning to play soccer. A player must learn to trap a ball, to dribble with a ball, to pass, and to shoot a ball. Once the player knows those basic skills, the next goals are to learn to play a position, to play certain strategies, to choose among feasible strategies, and, on occasion, to create variations of a strategy because none fits.

Question No: 21      ( M - 5 )
What is the purpose of the default statement?

The default statement is optional. If there is no case which matches the value of the switch statement, then the statements of default are executed.
